Appuatio mea November 10,1911. serial No. 659,617.

Tol all 'whom t may concern# Beit 'known 'that I, PHILIP W. Mo o1in, a

. citizen of the United. States,` residing at Evanston, in the county of Ooolrand State of Illinois, have invented new andv useful .Improvements in- Guard-Rail- Chairs, lof

, which the followingis a full, clear, concise,

and exact. description, reference being. had

I to the 'accompanying drawing, forming a part 'Of-this specification.. My invention relates to a combined guardrail chair and tie-plate.

' One of the objects of the invention is to- Y provide suitable abut-mentsor braces for the f main rail and guard-rail forproperly spacing these rails .and prevent them from mov- @Fig 5 isa perspective View ing-apart.

Another object is to provide a guard-rail lchair having the function Off' a tie-plate and having abutments or braces,lone o f which is g adjustable.-

A further object is to providespacing blocks, wedges 4or cheek pieces adapted-to be located. between the aforesaid rai-ls to 'force them firmly against the abutments or braces referred to, said blocks being held in place without-the use of' bolts' lor lotherl devices requiring holes or Openings/ through the rails.

Another object is block in the form of 'an adjustable chock,` adapted for all sizes of rails. V In-'the,accompanying` drawings I have illustrated a `simple and ment of my invention. Other embodiments are contemplated.

Referring to the drawings: Figure 1 is a topi plan `view of the form of guardrail .chair .and tieplate selected 4for the purposer -40 f illustration, shown 1n assembled position with respect to the two rails. Fig. 2 is an elevation l thereof withl they rails in section. Fig. Sis an endy elevationv thereof. Fig; 4 vis av fragmentaryl view of certain details. of a modified form of wedging blocks Or chock.

to provide a spacing l practical embodi-V arranged side by;4

1 with thevrail head 'located ,closer than would otherwise be the case and so that a suitable clearance may be provided'between theadjacent flanges of the rails for a purpose hereinafter set out.

It is essential that the two rails be properly bracedv to prevent them from moving apart.

5 at one endl oftheba's'e plate 3 and preferably vent an outward 'movement thereof.' The AccordinglyV I provide an abutment formed "`integrally therewith. 'Y lThis jaw. engages the base fof' the main rail l directly and grips the same firmly to preguard-rail lis firmly braced by -thelargen abutment or brace 6, which preferably' is 4 shapedrtoconformin general to the outline of the rail so that it will bear against the brace or abutment is adjustable with respect tothe-base 'plate 3 and is' adapted to be inovedwback and forth in ways or guides 7 which are preferably formedjintegral with fthe'end of saidba'se plate.V r'Ihe brace or abutment terminates preferably in'a wall portion 8 arranged somewhat diagonally with respect 'to the device as-a whole.` The diagonal wall bears directly lagainst the in of thewedge 9, which is pro clined .face vided preferably' though, of course,

with three: holes 10, al-

I Adonot limit myself tto any particular number, rPhe base 3 is provided preferably with two holes 11. One of the 'holes coincides with the upper hole inthe .wedge 9, withfthe parts inthe position seen in; Fig. l. The other` hole is shown in dotted lines. By moving thewedge 1n or outjuntil certain upper'and lower holes co.-

The'railsare spaced apart andiwedzed 'same both at the top and bottom. This. -I

incide, saidwedge maybe-spiked many- Vagainstthe lopposing abutments 5 and 6 by means oftw-o blocks or wedges 12 and 13,

y The block 12'- is preferably provided with 4a downwardly'- extending projeetioniv- Orilug'14 adapted to llit intolfa correspondingrslotgor recess 15 in forming an vadjustable chock.

theI hasey @hey-.lugylcoperati-ngwith events mQYement of said .block 'wedge 9 these members are interlocked in any posi; tion andprevented from a relative return movement which-would relieve the opposing thrust which they are intended 'to exert.

The parts are assembled as follows: The y is adjusted to approximately the desired position to permit the rails to be spread apart with their center li'nes about. the desired distance apart. .The block 12 4is then'put Ain place with itslug 14 fitting into'.v

in the' slot 15. The block 13 is then slid place as far as possible, although, of course, there is a certain looseness or play' due 'to thefact that the serrations or 'ribs on the adjacent faces of these` two blocks prevent a firm wedging engagement. By-d`riviu`g in the' wedge 9, however, the movable abut ment 6 forces the guard-rail 2 toward the main' rail land thereby forces the blocks 12 and 13 into firm locking engagement with each other.

If the rails are now found to be spaced thev proper distance apart, the wedge 9 may be secured in position by drivking a spike ,through one of the holes 10 therein andthrough some oneof the holes the base 3. The arrangement of holes is such that there are twoholes in more. or less vertical alinement in nearly any position of the wedge. If it is found, however, .that the rails are not spaced exactly wedge 9, instead of being spiked' into-position, is driven back and the block l13 is adjusted a distance of one or more teeth-'in one direction orl the other, whereupon the Wedge 9 is again driven home andmay be spiked in `place if the? spacing of-the rails is found to be correct. From the above description it will be apparent that the wedge 9 provides for general adjustments and the blocks 12 and 13 provide for minute adjustments. lFurthermore, it is a simple .mattertoprovide for rails of different sizes by providing ,different pairs of blocks,` all of which may have the' same lateral dimensions, but varying in vertical dimensions. Referring to Fig. 2,

- for example, it will be seenthat largerrail.`

' l The fillers or wedges may be of uniform l may be obtained will require llers of greater vertical height to ll inthe space between the under side of the head and the upper side of the base.

width, however, as any desired total width by the minuteadjustment referred to. 4

In- Fig. 5 I have illustrated a modified form of adjustable chock which may be adjusted not only to increase its total width but also its total height.l The chock comprises two blocks or wedge members 16 and 17 which have longitudinally inclined vertical walls provided with teeth or serrations similar to those described in connection with the preceding form of chock and having in addition coperating. faces which engage along a. plane inclined somewhat-from the asomo? or away from the base of the member 16.

The chock as a whole will therefore be en-` larged both in Width and in height, whereby Ait is adapted for use-with rails of all sizes.

of course, be`

The wedge member 16 may, provided with a downwardly extending lug (not shown) similar to that previously described. A chock' such as described is adapted for use in various relations, and is particularly-adapted for use in connection with the guard rail chair of the general form shown in the preceding figures. It is apparent that bolts are not required in connection with either form of chock dcs'cribed, the parts being held in the desired position by the interlocking teeth on the adjacent surfaces. This obviates the necessity of drilling a hole or providing a slot in the vertical web of the rail.

-The invention is not limited to the details shown and described, as I am aware that various changes may be made within the scope of the invention, as expressed in the appended claims.

What I claim as new and desire to secure by Letters Patent of the United States is:

1. A guard rail chair having a base plate adapted to support a main rail and a ard rail,' the latter having a portion o one flange removed to provide a clearance between the bases-of said rails, thereby giving access to an opening in said base plate an permitting adjustment of said rails toward and away from each other without covering said opening, a jaw formed integrally with one end of said base plate for gripping one ange ofthe 'ma-in rail, a sliding block mounted on the other end of said base and iitting against both the base .and the head of said guardrail to brace the same, ways in which `said block is guided, a wedge for de termining the position of said block,.said wedge having openings therein which are unequally 'spaced with reference to corresponding openings in said base plate whereby a spike may be inserted through a pair of registering openings, a pair of wedge blocks between said rails to hold them against the aforesaid outer abutf1ents, said wedges having interfitting engagement in a horizontal as well as in a of said wedges being of a length greater than the width of said base plate whereby a plurality of line adjustments of said blocks may be'obt'ained to vary the distance between said rails, said other block having a downwardly extending lug projecting into the opening of the-base platebetween said rail -baseswherevertic'al plane, onewww? said blocks are locked to'said base plate .and to each other Without'the use ofbolts.

'guardli'ail chair comprising, in com# bination, abutments adapted to bear against the main rail and theg'uaid rail to prevent Separation thereof, said abutments being adj'ust'abletoward and away from each other to provide fora pro-'per Spacing of said rails, and a chock adapted to he arranged between 'said rails to force theni against Said abut# ments; saicl chock comprising i members which are relatively movable in a plurality of planes, .whereby the eii'ectiye width and hei-ht of said chock may Ihe .varied to suit clinerent sizes of rails.

chock comprising Wedging blocks having two sets of ooperating faces engaging along planesi one. of which is' inclined verthcally and the 1other inclined horizontally,y whereby relative 'n'iove-nien't. of said blocks longitudinall)vv 'will cause an increase to atlaptthe saine for all sizes of rails. A

e. A chockcomprising ltwo coperating blocks engaging along' diagonally arranged surfaces, one block havingan upper and outer surface substantially equal to the width and height respectively of-said chock,

'both -ih the height and Width of said chock the other block having an outer and lower surface also equalrespectively to 4the height and width of said chock, whereby Said chock may engage adjacent rails and properly Space themapart vin various positions of acljustinentadapted to varying sizes of 'ra-ils.

In Witness whereof, l have .hereunto-subscribed my name in the presence of two Wit--
